Using trusted node sync currently requires to run two commands -
first the `trustedNodeSync` command to initialize the database,
followed by the regular startup command to continue syncing.
The `trustedNodeSync` options are now also available during regular
startup, and are used when the database is empty to simplify setting up
a new Nimbus beacon node. This also aligns behaviour closer with other
Ethereum consensus implementations.
The new logic only applies if the database has not yet been initialized;
same as before. Also, the database needs to be removed under the same
conditions as before when a fresh sync is desired.
- compact syntax for different options (as in the rest of the guide)
- correct numeration of the list (continuation vs starting from 1)
- add links to useful resources
- a note stating that Prater is deprecated
* Add metadata for the Holesky network
* Add copyright banner to the new Nim module
* Working version
* Bump Chronos to fix downloading from Github
* Add checksum check of the downloaded file
* Clean up debugging code and obsolete imports
I couldn't install those packages with the versions previously stated.
The new versions install successfully,
and `make publish-book` works without errors.
* make the validating guide self-contained
Instead of having links to the three separate how-to guides,
now everything is under one umbrella.
* fix all now-broken links
* Apply suggestions from code review

* Incremental pruning
When turning on pruning the first time the current pruning algorithm
will prune the full database at startup. This delays restart
unnecessarily, since all of the pruned space is not needed at once.
This PR introduces incremental pruning such that we will never prune
more than 32 blocks or the sync speed, whichever is higher.
This mode is expected to become default in a follow-up release.
Post-Capella, historical roots are computed from historical summaries
instead of being directly stored in the beacon state.
Slightly messy to pass both lists around - this is done to avoid
computing the historical root unnecessarily.
* part 2 of the initial doc fixes
- spelling fixes
- grammar fixes
- em-dashes should be em-dashes (`—`): double dashes (`--`) are not rendered properly
- reduce overusage of em-dashes, some of those should be separate sentences
- use the correct syntax for notes, tips and warnings
- every sentence is in a separate line (helps with future diffs)
- add missing dots at the end of list items
- fix some lists
* sentences on separate lines in the remaining files
- spelling fixes
- use the correct sintax for notes
- em-dashes should be em-dashes (`—`): double dashes (`--`) are not
rendered properly
- fix a link (was to a .html, should be to .md)
- add missing dots
- every sentence should be on a separate line: it makes future diffs
much nicer and easier to spot the changes
* Support for driving multiple EL nodes from a single Nimbus BN
Full list of changes:
* Eth1Monitor has been renamed to ELManager to match its current
responsibilities better.
* The ELManager is no longer optional in the code (it won't have
a nil value under any circumstances).
* The support for subscribing for headers was removed as it only
worked with WebSockets and contributed significant complexity
while bringing only a very minor advantage.
* The `--web3-url` parameter has been deprecated in favor of a
new `--el` parameter. The new parameter has a reasonable default
value and supports specifying a different JWT for each connection.
Each connection can also be configured with a different set of
responsibilities (e.g. download deposits, validate blocks and/or
produce blocks). On the command-line, these properties can be
configured through URL properties stored in the #anchor part of
the URL. In TOML files, they come with a very natural syntax
(althrough the URL scheme is also supported).
* The previously scattered EL-related state and logic is now moved
to `eth1_monitor.nim` (this module will be renamed to `el_manager.nim`
in a follow-up commit). State is assigned properly either to the
`ELManager` or the to individual `ELConnection` objects where
appropriate.
The ELManager executes all Engine API requests against all attached
EL nodes, in parallel. It compares their results and if there is a
disagreement regarding the validity of a certain payload, this is
detected and the beacon node is protected from publishing a block
with a potential execution layer consensus bug in it.
The BN provides metrics per EL node for the number of successful or
failed requests for each type Engine API requests. If an EL node
goes offline and connectivity is resoted later, we report the
problem and the remedy in edge-triggered fashion.
* More progress towards implementing Deneb block production in the VC
and comparing the value of blocks produced by the EL and the builder
API.
* Adds a Makefile target for the zhejiang testnet
